  • Since the internal motions of proteins play an essential role in their biological function, it is important to characterize them in a fundamental way. The Lindemann criterion for the solid state is applied to molecular dynamics simulations and temperature-dependent X-ray diffraction data of proteins. It is found that the interior of native proteins is solid-like, while their surface is liquid-like. When the entire protein becomes solid-like at low temperature ( approximately 220 K), the protein… CONTINUE READING
